RedTacton is a new Human AreaNetworking technology that uses the

surface of the human body as a safe,

high speed network transmission

path.

It uses the minute electric field emitted

on the surface of the human body.

A transmission path is formed at

the moment a part of the human

body comes in contact with a

RedTacton transceiver.

Communication is possible

using any body surfaces, such

as the hands, fingers, arms,

feet, face, legs or torso.

The transmitter sends data by inducing fluctuations in the minute electric field onthe surface of the human body. Data is received using a photonic electric field

sensor that combines an electro-optic crystal and a laser light to detect fluctuationsin the minute electric field.

Touching, gripping, sitting,

walking, stepping etc can bethe triggers for unlockingor locking, starting orstopping equipment, orobtaining data.

In addition to the humanbody, various conductorsand dielectrics can beused as transmissionmedia.

The transmitting and receiving electrodes

of the RedTacton transceiver arecompletelycovered with insulating film, so the body of theperson acting as the transmission medium is

completely insulated. This makes it impossiblefor current to flow into a persons body fromthe transceiver.

RedTacton conforms to the Radio

Frequency-ExposureProtection Standard (RCRSTD-38) [6] issued by the Association of

Radio Industries and Businesses (ARIB). The

CONCLUSION

RedTacton is an exciting new technology for humanarea networking.

While our immediate objective is to implement aRedTacton system supporting two-way intrabodycommunication at a rate of 10 M bit/s between

any two points on the body. Our longer-term plans include developing a mass-

market transceiver interface supporting PDAs andnotebook computers while continuing efforts to

reduce the size and power consumption of thetransceiver to enhance its portability.
